Detailed Description

template<int8_t ALGORITHM>
class WavePacketSample< ALGORITHM >

A WavePacket which allows a custom table to be set as the audio source for the wavepackets (or grains).

Template Parameters

ALGORITHM

options are SINGLE or DOUBLE, for a single non-overlapping stream of packets or a double, overlapping stream.

Member Function Documentation

next()

template<int8_t ALGORITHM>

int WavePacket< ALGORITHM >::next ( )

inlineinherited

Calculate the next synthesised sample.

Returns

a full-scale 16 bit value, which needs to be scaled to suit your sketch. If you're using it straight as the sketch output, then that will be yourThing.next()>>2 for HIFI 14 bit output, or >>8 for STANDARD 8+ bit output.

Definition at line 113 of file WavePacket.h.

set()

template<int8_t ALGORITHM>

void WavePacket< ALGORITHM >::set ( int  fundamental, int  bandwidth, int  centrefreq  )

inlineinherited

Set all the parameters for the synthesis.

The function is designed so that usable ranges for parameters can come from analog inputs, ie. 0-1023.

Parameters

fundamental	the rate at which packets are produced.
bandwidth	the width of each packet. A lower value allows more of the centre frequency to be audible, a rounder sound. A higher value produces narrower packets, a more buzzing sound.
centrefreq	the oscillation frequency within each packet.

setBandwidth()

template<int8_t ALGORITHM>

void WavePacket< ALGORITHM >::setBandwidth ( int  bandwidth )

inlineinherited

Set the bandwidth.

The function is designed so that usable ranges for parameters can come from analog inputs, ie. 0-1023.

Parameters

bandwidth

the width of each packet. A lower value allows more of the centre frequency to be audible, a rounder sound. A higher value produces narrower packets, a more buzzing sound.

Definition at line 85 of file WavePacket.h.

setCentreFreq()

template<int8_t ALGORITHM>

void WavePacket< ALGORITHM >::setCentreFreq ( int  centrefreq )

inlineinherited

Set the centre frequency.

The function is designed so that usable ranges for parameters can come from analog inputs, ie. 0-1023.

Parameters

centrefreq

the oscillation frequency within each packet.

Definition at line 100 of file WavePacket.h.

setFundamental()

template<int8_t ALGORITHM>

void WavePacket< ALGORITHM >::setFundamental ( int  fundamental )

inlineinherited

Set the fundamental frequency.

The function is designed so that usable ranges for parameters can come from analog inputs, ie. 0-1023.

Parameters

fundamental

the rate at which packets are produced.

Definition at line 70 of file WavePacket.h.

setTable()

template<int8_t ALGORITHM>

void WavePacketSample< ALGORITHM >::setTable ( const int8_t *  TABLE_NAME )

inline

Change the sound table which will be played.

Needs to be 8192 cells long for now.

Parameters

TABLE_NAME

is the name of the array in the table ".h" file you're using.
